UD_ANOVA_stage: Stage-wise uncertainty based on the second order interaction ANOVA

Description

This function performs uncertainty decomposition by stage based on the second order interaction ANOVA model. The uncertainty from interaction effect from two stages is divided equally and assigned to each stage.

Usage

UD_ANOVA_stage(data, var_name, stages = setdiff(names(data), var_name))

Arguments

data

a data frame containing models(factor or character) for each stages and the variable of interest(numeric). data should contain all combinations of models.

var_name

the name of the variable of interest

stages

names of the stages in the model.

Value

List(UD_stage class) including uncertainties of stages, uncertainties from main effects, uncertainties from interaction, total uncertainty, names of stages.

Examples

# NOT RUN {
set.seed(0)
stage1 <- LETTERS[1:3]
stage2 <- LETTERS[1:2]
stage3 <- LETTERS[1:4]
y <- rnorm(3*2*4)
data <- expand.grid(stage1=stage1,
                    stage2=stage2,
                    stage3=stage3)
stages <- names(data)
data <- cbind(data, y)
UD_ANOVA_stage(data,"y", stages)
# }
